The tensile opening of Kodaly's Sonata for Solo Cello, Allegro maestoso ma appassionato commences with powerful declamatory writing that gradually opens-out in expression while also evincing greater harmonic ambiguity. This second main theme unfolds at some length, before an extensive development in which technical virtuosity is pushed to the limit. The reprise duly centers on the second theme, though elements of its predecessor never seem far away. Even when the music withdraws into itself for an inward coda, the closing brusque gesture makes for an unequivocal statement of intent.
